Getting Started
2-2
Starting the UC-7400-CE
Connect the SG wire to the shielded contact located in the upper left corner of the target computer,
and then power it on by connecting it to the power adaptor. It takes about 30 to 60 seconds for the
system to boot up. Once the system is ready, the “Ready” LED will light up and remain lit until
you shut down the computer. For a computer with an LCM display, the network address settings
and other system information will appear on the LCM.
Resetting the UC-7400-CE
Warm/Cold Start:
You seldom need to perform a warm start or cold start on the UC-7400-CE
computer. In some cases when the computer stops responding, an application locks up, or when
you upgrade the firmware, it may be necessary to perform a warm start or a cold start.
Warm Start:
In the power-on state, insert a pin into the “Reset” hole next to the serial ports and
hold the pin in for 1 or 2 seconds. This will cause the computer to reboot.
Cold Start:
Switch off the power and then switch the power back on. The computer will reboot
itself right away.
Resetting to Factory Defaults:
If the computer is not working properly, and you want to reset it
back to the factory default settings, press and hold the “Reset to Default” button for at least 5
seconds. The buzzer will sound when the factory default settings are loaded. After the factory
default settings have been loaded, the computer will reboot itself. Do not confuse this with the
“Reset” button.
Operating the UC-7400-CE from the Serial Console
The serial console port (located next to the two LAN ports) gives users a convenient way of
connecting the development workstation to the console utility of the target computer. This method
is particularly useful when using the target computer for the first time.
After connecting the serial cable, start a terminal program (e.g., HyperTerminal) from the
development workstation by using the settings shown below for the serial console port.

The console has a default timeout value of 15 minutes. To disable the timeout, you will need to
change a value in the registry. Go to “
HKEY_LOCAL_MACHINE\Comm\CONSOLED
”, and
set the “
Timeout
” value to “FFFFFFFF”.
